Abstract
The invention relates to a method for producing and securing a screw in a preset position to prevent unauthorized adjustment. The screw securing means according to the invention makes it possible to secure a screw connection in a simple manner, in that a screw head of thermoplastic plastic, which is at least partly located in a housing recess, is heated to such an extent that it changes to the liquid state, flows into the housing recess, and at least partially fills the housing recess. By form-fitting engagement with the threaded pin and the housing recess, security against twisting, and also against being rotated without authorization, is attained. Screws in components that vibrate severely, and adjusting screws that must not be adjusted by unauthorized third parties, can be secured with this screw securing means.
